Homework Statement
A 200g mass attached to a horrizontal spring oscillates at a frequency of 2.0 Hz. At one instant, the mass is at x=5.0cm and has vx = -30cm/s.
A. Determine the period. T= ____seconds
B. Determine the amplitude. A =____cm
C. Determine the maximum speed. vmax = ____ cm/s
D. Determine the total energy. ____ J
Homework Equations
A. T = 1/frequency
B. ?
C. vmax= 2(pi)(f)(A) = 2piA/T
D. ?
Others: deltaL = mg/k where k=spring constant
The Attempt at a Solution
A. Answer = 0.5 seconds from T = 1/f... T = 1/(2.0Hz)... T=0.5 secods
B.
C. vmax=2pi(2.0Hz)(A)
D.
I'm not looking for just the answers; I am in desperate need of an explanation of HOW to do the problem. Any help is greatly appreciated!
